The pressurization smoke control system has become a standard for smoke control systems in high-rise buildings. Pressurization smoke control systems can incorporate features to deal with pressure fluctuations due to the opening and closing of doors. These features include pressure-relief vent and variable-supply air fans. In this study, ratio of supply air volume to leakage area of a pressurized room was defined as an evaluation value for the pressure control. Relations between the defined values and pressure control characterization as setting time and maximum pressure difference were examined by experiments using an mock-up model and field measurements in actual buildings. A design method of the pressure control system was proposed from the experimental results.
